Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538926, here are decompositions:

137 + 31538789 = 31538926
173 + 31538753 = 31538926
197 + 31538729 = 31538926
233 + 31538693 = 31538926
347 + 31538579 = 31538926
449 + 31538477 = 31538926
593 + 31538333 = 31538926
599 + 31538327 = 31538926

Showing the first eight; more decompositions exist.
